LISTING-PLOW.

Specification of Letters Patent.

Patented Apr. 22, 1913.

Application filed March 22, 1912. Serial No. 685,537.

To all whom it may concern:

Be it known that I, Go'rrrRID PERssoN, a citizen of the United States,residing at Lueders, in the county of Jones and State of Texas, haveinvented a new and useful Listing-Plow, of which the following is aspecification.

This invention relates to listing plows and is more particularly animprovement upon the structure disclosed in Patent No. 866,679, issuedto me on September 24, 1907.

One of the objects of the invention is to provide a combined listingplow and cultivator having listing disks arranged in pairs adjacent thesides of the plow, one disk of each pair being disposed in front of theother disk of the pair and the two disks of said pair being oppositelypitched.

A further object is to provide a structure of this character in whichthe shovel and the dropping mechanism is located directly back of thepairs of disks.

A further object is to provide improved means for raising and loweringthe frame of the plow together with the disks and other parts carriedthereby.

With the foregoing and other objects in view which will appeafas thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodimentof the invention herein disclosed can be made within the scopeof what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings :-Figure 1 is a plan view of the plow. Fig. 2 is a sideelevation thereof, the near supporting wheel being re moved. Fig. 3 is aperspective. view of the colter blade used in connection with theplanting mechanism and showing the means for connecting the same to theplow structure. Fig. 4 is a view similar to Fig. 3 but showing means forconnecting the plow stock to the machine in lieu of the colter blade,when the machine is not to be used for planting. Fig. 5 is a verticaltransverse section through a portion of the guide plate and itsextension and showing one of the braces and the rack bar. Fig. 6 is aperspective view of the lapping portions of the front cross strip andshowing the bracket carried by one of said portions.

Referring to the figures by characters of reference 1 designates sidebeams each of which has laterally extending converging arms 2 secured toa guide plate 3. This plate has a downwardly extending portion 4 formedalong its sideedges with guide flanges 5. A guide ear 6 or the likeextends from one end of the plate 3 adjacent the top thereof and thisear, as well as the flanges 5, is adapted to be slidably engaged by arack bar 7. A spindle 8 extends laterally from the lower portion of therack bar and is supported by one of the wheels 9 of the machine. A brace9 extends from the side beam 1 downwardly to the lower end portion ofthe extension 4, as shown in Fig. 5, and thus it will be seen that theplate '3 and its extension 4 will be held fixed relative to the adjacentside beam 1 under all conditions.

The two side beams 1 are connected by cross strips 10 and 11 disposed inlapped relation, the lapping portions thereof being provided withlongitudinal slots 12 for the reception of clamping bolts 13 or thelike. Crossed braces 14 are preferably secured to the beams 1 close tothe rear cross strips 10 and 11 and the front ends of these crossedbraces are preferably secured to the front cross strips 10 and 11 bymeans of the bolts 13. Slots may be formed in the front ends of thebraces 14, as shown at 15, so as to permit these braces to shiftrelative to the cross strips when it is desired to adjust the beams 1toward or from each other so as to thus reduce or mc-rease the wldth ofthe machine.

Arms 16 extend upwardly from the front end portions of the beams 1 andsecured on these arms are thills or parallel draft beams 17. V-shapedextensions 18 are bolted or otherwise secured to the inner faces ofthese thills adjacent their inner ends and are connected by a cross bar19 having a central opening 20. This openin registers with an opening 21formed in a bracket 22 extending forwardly from the front cross strip10. A fastening pin 28 is adapted to be inserted into these openings andlikewise to extend through an opening formed in the center of a pivotedtransverse draft beam 24 which projects between the bar 19 and thebracket 22. Equalizer levers 25 are pivotally connected to the outerends of beam 24 and the inner ends of these levers are connected bylinks 26 to a whiffletree 27 located below the space between the thills17 A whifiletree 28 may be connected to the outer end of each lever 25.

Secured to each beam 1 at points in ad vance of the arm 9 are downwardlyconverging arms 29 and another pair of down wardly converging arms 30extends from the beam 1 at points back of the brace 9. Each pair of arms29 and 30 has a stud 31 extending therefrom at its lower end andconstituting a bearing for a lister disk 32. The studs of the two pairsare disposed at different angles so that the disks carried thereby willbe held substantially at right angles to each other and one directly infront of the other.

A shaft 33 is journaled on each side beam '1 and on the adjacent guideplate 3 and is provided, at its outer end, with a segmental gear 34which meshes with the rack bar 7 located at one side thereof. A lever 35is secured to the inner end of each shaft 33 and a toothed segment 36 ismounted on beam 1 close to the lever and is adapted to be engaged by apawl 37 carried by said lever so that the lever and shaft 33 can thus besecured against movement.

A hanger 38 extends from the rear end of each beam 1 and is provided,near its lower end, with a side enlargement 39 from which extends an arm40, said arm being bolted or otherwise secured to a hanger 41 extendingfrom the beam 1 and engaged by one end of the stud 31 of the rear disk32. A colter blade 42 extends across the enlargement 39 and is heldthereon by a saddle 43 which straddles the blade and also theenlargement and is bolted or otherwise fastened in place as indicated at44. The lower portion of the blade 42 is curved downwardly andrearwardly and terminates in a fork 45 adapted to receive the outletspout or boot 46 which extends downwardly from a feed box 47 carried onthe rear end portion of the beam 1. The colter blade 42 is locateddirectly back of the centers of the disks 32 and constitutes a means forcutting the levers 35, the gears 34 can be rotated so as to permit theguide plates 3 and their extensions 4 to slide downwardly on the rackbars 7 thus to bring the listing disks 32 into engagement with the soil.When the machine is moved forward these disks will operate to throw thesoil to opposite sides of the furrow produced by the disks and thecolter blade 42 following in this furrow will produce a final cut in thesoil to receive the seeds deposited from the boot 46.

here the device is used solely for listing, shovels may be substitutedfor the colter blades. Each of these shovels includes a stock 48having-a blade 49 fastened to the lower end thereof, the said stockbeing extended between the saddle 43 and the enlargement 39, as shown inFig. 4. This shovel will travel in the center of the furrow produced bythe disks 32 and can be adjusted so as to plow to any desired depthwithin the furrow.

\Vhenever it is desired to shift the soil engaging elements upwardly soas to prevent them from tilling the soil, the segmental gears 34 areactuated so as to push the guide plates 3 and their extensions 4downwardly along the rack bars 7, thus to bring the wheels 9 below theplane occupied by the lower edges of the soil engaging devices, and asshown in Fig. 2.

What is claimed is The combination with a wheel supported structure, ofa pair of listing disks carried by the structure and disposed onedirectly in front of the other, said disks being pitched to throw thesoil toward opposite sides of the path of the disks respectively, ahanger depending from the structure and back of the disks, anenlargement thereon, a saddle engaging the enlargement, and a soilengaging element detachably and adjustably held to the enlargement bythe saddle.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
